Description

one

The invention relates to the field of the textile industry and relates to a device for feeding a spinning machine with a carding tape.

A known spinning machine is advantageously used for faceless spinning, in which for each workplace there are containers for the tape supplied in the cans from the prep department.

The iB of the proposed spinning machine for reducing the number of transportable pelvic containers is mounted inside the machine under the workplaces with the possibility of moving from one workstations to the machine. In this case, the machine is equipped with at least one device for transferring the tape from the pelvis to the tank, moved by a system of conveyors.

FIG. Figure 1 shows schematically a spinning machine with a tape shifter, front view; in fig. 2 shows the layout of the ribbon containers with one device for placing the tapes from the cans, plan view; in fig. 3 shows the arrangement of the containers for the belt with the device for their transportation (section A-A in FIG. 2); on fit. 4 shows the drive for the containers (section along BB in FIG. 3); in fig. 5Схе2

the location of the containers with simultaneous transverse movement of their rows; in FIG. 6 - spinning machine with two gears for shifting the belt, plan view.

On the spinning machine (see Fig. 1), on the side opposite to the actuator /, a device 2 is installed for shifting the tape 3 from the pelvis 4 filled with the tape on the previous machine of the preparatory department in the tank 5 for feeding each work station (straight unit 6 ). The containers 5 are located inside the spinner (Machines for UNDER workplaces with the possibility of moving them relative to the workstations, and the containers always remain with the machine.

The fixing device 2 for shifting the belt consists mainly of a rotating plate covered with a casing, serving as a tape feeding mechanism. Capacity 5 is made in the form of small diameter basins.

For tanks 5, the spinning machine has several, for example four, paths of movement Ki, Ki, Kz, K (see Fig. 2).

On the path x / Ci and K there are filled containers, of which combing tape 3 is fed to the spinning unit 6. On one of the other paths of K.2 or / Cz are empty containers to be filled with tape 5.

The containers are transported inside the machine through a system of belt or chain conveyors, passing under their bottom. Transportation of containers when they are located on the outside, the outer paths Ki and K are produced respectively by chain 7 and 5, and transportation of containers on the internal railways K-2, K.b. is a common common chain 5. For capturing containers on the chain the conveyors are reinforced by the cams 10, and the direction of movement is carried out by the guide wheels 11. The chains of the conveyors are driven by a reversing electric motor 12, which rotates the copy gears 13-15 and sprockets 16-18 rigidly connected found in gearing chains TpaiHcnoipTepoB. The conical jibs are mounted on shafts 19-21, the connection between the drive shaft 20 and the driven shafts 19 and 21 is performed by switching 22 and 23.

The iB of the spinner 5 of the tank 5 passes between the guide strips 24 and 25, and the guide strips of the inner tracks / Ca and / Cz At the ends opposite to the device 2 for shifting the tape are connected to the guide tracks of the outer tracks K and / (4, as a result of which 5 can be moved from one path to another, and near the tool 2 between the paths, there are rotary shutters 27 and 2S pivoted around the axes 26.

After the emptied emptied containers with p | ia1i K, go the path / Sz, the shaft 20 begins to move the containers towards the device 2 for filling them with tape. At the same time, the shutters 27 and 28 are turned about the axes 26 in such a way that the containers filled with lenga by the transport chain 9 are directed to the path Kz (along the arrow P, fig. 2).

| As soon as all containers are filled and transfer to the Kz path, the filling circulation stops - the tanks are prepared to be transferred to places 6 on the left side of the machine (path / Ci) and when the tanks on this side are empty, they are replaced by the filled ones. capacitors from path K.2. A change will occur (along arrow A, 1FIG. 2) with flap 27 slid over (1FIG. 2 is shown in dashed lines), which closes the path / C3. In this case, the shaft 19 for putting the chain 7 into motion through the sprockets 16 is connected to the shaft 20 by means of the coupling 22. The chain 7 empties the containers to the path Kz, being carried by the cams of the chain 9 and the total capacitance is intercepted by the value 7.

After the capacitance is changed, the connection between Shaft 20 and shaft 19 is disconnected, guide valve 27 is turned back | (shown in Fig. 2 as a flat line), "electric motor 12 reverses, and as a result, capacitive tanks on the way Kz gradually move chain 9 to the shifter 2, are filled with tape and transported onto the path / Sz (along the arrow of the RZ) for the subsequent passage onto the path K. to the work stations on the right side of the machine (along the arrow 4).

With this design, the replacement of empty containers filled with tape is carried out alternately for each side of the machine. Before replacing the containers, the workstations 6 on the side where the banners occur are stopped.

I also connect the paths / d, / (2, / (3 and 1) to connect with each other, and to direct the containers and at the remote ends from the paraglider 2, to establish between the paths rotary dampers, which allows the containers to move past at the same time replace the containers that are on the path K «K.

The change of containers can be carried out by simultaneous transverse nepeiMeshcheni rows of empty and filled containers (see Fig. 5). In this case, of the five paths / Ci, 4, K.Z, Ks and / C, the three paths are completely filled with containers, and in the previous cases, Ki and K receive tape-filled containers for feeding the workplaces 6 maschins.

On one of the paths / Cs or K are empty containers. When it is necessary to prepare a change of containers for the places of strand 6, for example, on route K, at this time the path / Cs turns out to be empty containers. These containers arrived at the blow / Cs after emptying the tanks on path K. .. Empty tanks are conducted (along the cages Re, PI past the slider 2, filled with carding tape and diverted to path / C (arrow P &}). Replacing the station The empty containers filled on the path / C4 are filled by simultaneously moving both rows / СБ and К across the path (along the РЭ arrow). At the same time, the empty containers 5 go from path K to path / С, and from path / Се filled containers on p | ut K /, after which a new turnover begins filling the empty containers from the path / C / (along the arrows, RP) to the transfer device 2 and further onto the path / Ce (along the arrow P &) to prepare for shifting to the path / Ci (along the arrow Pi2).

With this construction, the time required for changing the containers is shortened; moreover, as in the previous cases, the replacement of the containers is carried out alternately for the side of the spinning machine, and the filling of the containers with the ribbon is carried out from one adaptation 2 for shifting the tape.

The spinning machine can also be equipped with two devices for shifting the tape (see Fig. 6), which makes it possible to simultaneously replace the containers on both sides of the machine.

Capacities 5, from which to places of the day

6 a carding tape is fed, located on the paths x / Ci and K. Empty containers from these paths enter the paths Ks and Kg. (When filled with tape, they are transported by a transport chain to their shifting device 2 or 2 (according to arrows Рв and РГ or РЮ, Рц) and filled with tape, after which they are transported on the way Ki; and Kv (lines PS and Ps) Upon completion of this movement of the tanks, the paths Ke and / Sat are completely occupied by the containers filled with tape.

Chargeings of emptied containers on paths K and Kt occur simultaneously on both sides of the spinning machine through simultaneous transverse movement (respectively, according to the REM and PIS arrows), as a result of which containers filled with path K go to path K :, and containers with path K

on the path K, and the emptied containers are moved along the path Kj and Kt, and the cycle repeats.

Subject invention

The spinning machine is predominantly for ringless spinning, which has containers for each workplace.

the ribbons supplied in the basins from the machines of the prep department, in order to reduce the number of transported basins, the tanks are mounted inside the machine under the workplaces with the possibility of movement relative to the maschine workstations, and the machine is equipped with at least , one device for transferring the tape from the pelvis to the tank, transported by means of a transport system.
